As shown in Figure 1, a kind of system architecture diagram of realizing bandwidth control that provides for the embodiment of the invention.In user's home network, have a plurality of terminals that Network can be provided, these terminals are by the network equipment of HGW (home gateway, home gateway) access far-end.Can access Internet such as the PC among Fig. 1 (personal computer, PC), STB (set top box, set-top box) can access IPTV platform (IPTV platform) etc.By in the terminal that the IPTV business can be provided, selecting the manager of an access bandwidth, come to distribute and the recovery bandwidth resources for the other-end in the home network.Wherein the selected manager who does access bandwidth is called the office terminal, and other except the office terminal can provide the terminal of IPTV business to be called and be managed terminal.Each is managed terminal before opening the IPTV business, need to be to office terminal bandwidth application resource, and whether the office terminal determines for being managed the terminal distribution bandwidth resources according to the bandwidth left amount.Being assigned with the terminal that is managed of bandwidth resources, can to open self IPTV professional.Embodiment 1:

Based on system architecture diagram shown in Figure 1, the embodiment of the invention provides a kind of method that realizes bandwidth control, relates to office terminal one side, as shown in Figure 2, comprising:

201, the office terminal in the home network sends administrative messag to the terminal that is managed in the described home network.

This administrative messag comprises default address list, comprises the address that is managed terminal that is assigned with bandwidth in address list.

202, receive the response message that is managed the terminal transmission in the described home network.

Wherein, when not being included in the described address list in the described address that is managed terminal, described response message comprises the described bandwidth demand amount that is managed terminal.

Need to prove, for the terminal that is managed that is not assigned with bandwidth, in the response message of its feedback with the bandwidth demand amount that requires; And be recorded in the terminal that is managed in the address list for the address, namely be assigned with the terminal that is managed of bandwidth, there is not the bandwidth demand amount in the response message of its feedback, and can carry a confirmation, this situation is equivalent to the office terminal and is managed terminal confirm that by administrative messag and response message both sides are in connection status.

203, comprise described bandwidth demand amount when described response message, and when remaining bandwidth is not less than described bandwidth demand amount, be the described terminal distribution bandwidth that is managed according to described bandwidth demand amount, and the described address that is managed terminal is increased in the described address list.

The office terminal is accessed the remaining bandwidth that total bandwidth judges that the user accesses total bandwidth according to the user of pre-save and whether is not less than the bandwidth demand amount that is managed terminal, wherein, the user accesses the access bandwidth that total bandwidth is the IPTV business that all have been opened in the home network.

The office terminal can send administrative messag according to the default management cycle in home network, wherein, and non-limiting, the above-mentioned default management cycle of mentioning specifically can be 1 second cycle as example.

After being managed terminal and receiving administrative messag of bandwidth on demand demand, when finding the address of self in address list, it is professional that the bandwidth of distributing according to the office terminal starts IPTV.

The below describes step 201 to step 203 for example:

For instance, when if the user uses IPTV professional at home, when some be managed starting up of terminal after, when receiving the administrative messag that the office terminal sends, be managed terminal and send response message to the office terminal, comprise this address that is managed terminal and bandwidth demand amount in the response message.The office terminal judges according to user's access bandwidth of pre-save whether remaining bandwidth is not less than the bandwidth demand amount.When remaining bandwidth was not less than the bandwidth demand amount, the office terminal was for being managed the terminal distribution bandwidth, and the address that will be managed terminal joins in the address list, and the administrative messag that will comprise address list sends in home network.After being managed terminal and receiving administrative messag, find that self address in address list, then starts the IPTV business; When the office terminal is found remaining bandwidth less than the bandwidth demand amount, the office terminal can not add address list with the address that is managed terminal, can not distribute bandwidth yet, therefore being managed terminal can not find the address of self in the address list of the follow-up administrative messag that receives, and can not start the IPTV business.After this, be managed terminal and will continue the administrative messag that the receiving management terminal sent by the default management cycle, and continuation sends response message, the address and the bandwidth demand amount that comprise self in the response message, in case when the office terminal finds that remaining bandwidth is not less than the bandwidth demand amount that requires in the response message, will be required the terminal that is managed of bandwidth to carry out allocated bandwidth.

It is to be noted, when being managed terminal and just having started shooting, this address that is managed terminal may be present in the address list of office terminal, the office terminal is before the address that will be managed terminal adds address list, need to check whether Already in address list of this address that is managed terminal, if exist, then need not repeat to add.Preferred scheme is in the practical application, when the office terminal begins to reach the standard grade, empty first address list, and roll off the production line in case be managed terminal, then the address that this is managed terminal will be deleted in the office terminal in address list, can guarantee that like this address of himself can not be present in the address list when reach the standard grade in the office terminal.

On the other hand, embodiments of the invention also provide a kind of method that realizes bandwidth control, relate to being managed terminal one side, as shown in Figure 3, comprising:

301, the terminal that is managed in the home network receives the administrative messag that the office terminal in the described home network sends.

Described administrative messag comprises address list, and described address list comprises the address that is managed terminal that is assigned with bandwidth.

If 302 described address lists do not comprise the described address that is managed terminal, then send response message to described office terminal, described response message carries the described bandwidth demand amount that is managed terminal.

By response message so that the office terminal is when remaining bandwidth is not less than described bandwidth demand amount, according to described bandwidth demand amount for being managed the terminal distribution bandwidth.

In the office terminal according to the bandwidth demand amount for after being managed the terminal distribution bandwidth, will be managed the address of terminal add address list, and address list is added in the administrative messag, then in home network, send this administrative messag.Be managed terminal and receive the address of finding self in administrative messag and therein the address list, be managed terminal this moment and know that the office terminal distributed the professional required bandwidth of IPTV.Do not start the IPTV business if be managed terminal, then be managed starting terminal IPTV professional.

The method of the realization bandwidth control that the embodiment of the invention provides sends administrative messag by the office terminal in the home network to the terminal that is managed in the home network, and the address list record that this administrative messag comprises has been assigned with the address that is managed terminal of bandwidth; After being managed terminal and receiving administrative messag, if the address that is managed terminal then requires bandwidth by response message to the office terminal not at this address list; The office terminal when remaining bandwidth is not less than the bandwidth demand amount that is managed terminal for being managed the terminal distribution bandwidth, start the IPTV business in order to be managed terminal according to the bandwidth that is assigned with, pass through such scheme, so that when the remaining bandwidth deficiency, and when the same IPTV of a plurality of terminal accesses is professional, can guarantee that at least one terminal can carry out Operational Visit glibly.

Embodiment 2:

The embodiment of the invention provides a kind of method that realizes bandwidth control, as shown in Figure 4, take three terminals as example describes, is called first terminal in Fig. 4, the second terminal and third terminal, and the terminal quantity in the actual conditions is not limited to this.The method of realization bandwidth control shown in Figure 4 specifically comprises:

401, first terminal judges whether to receive administrative messag within the default management cycle after finishing login.

Behind certain starting up of terminal in the middle of family's network, at first login in the IPTV operation system, after logining successfully, obtain the user from the IPTV operation system and access total bandwidth, be kept in the terminal, and oneself state is set to interim state, detects in network, to judge whether receiving administrative messag within the default management cycle.

Concrete, the terminal in the home network can be by the state of a state machine management self when oneself state is set.Each terminal has three kinds of states: one, manager when the state of terminal is the manager, can be non-management person's terminal distribution bandwidth and reclaims bandwidth resources for state.Two, non-management person when the state of terminal is the non-management person, to manager's bandwidth application, and waits for that the manager distributes bandwidth for self.Three, interim state is behind starting up of terminal, can oneself state be set to interim state, when finding there has been the manager in the middle of the home network, and during to the success of manager's bandwidth application, oneself state is set to non-management person is interim state in other situation.Be unified explanation, state is all called after office terminals of gerentocratic terminal in the embodiment of the invention, state be the non-management person terminal all called after be managed terminal.

And non-limiting, the above-mentioned default management cycle of mentioning specifically can be 1 second cycle as example.

402, when not receiving the administrative messag that sends the office terminal within the default management cycle, first terminal is broadcasted election message in home network, and described election message comprises the address of first terminal.

403, when the response that within the default stand-by period, do not receive for election message, first terminal with self as the office terminal, beginning broadcast management messages in home network.

The mentioned default stand-by period specifically can be 3 seconds cycle in the embodiment of the invention, also can be other cycle, is arranged voluntarily according to the actual conditions of the network operation by the user, and the present invention is not construed as limiting this.

The below describes step 401 to step 403:

After the first terminal start, login in the IPTV operation system, after logining successfully, whether judgement receives administrative messag in home network, if when within the management cycle, not receiving administrative messag, so at this moment, there is not the office terminal in the home network, first terminal can be broadcasted election message election contest office terminal in home network, if within the default stand-by period, do not receive the feedback message of election message, first terminal can be with own as the office terminal so, and in home network broadcast management messages, comprise address list in this administrative messag, address list empties when initialization, the address of namely not recording any terminal in the address list in the administrative messag that sends for the first time of office terminal.If after at this moment other-end (such as, the second terminal) start was arranged, then execution in step 404 was to step 415.

404, after the second terminal receives the administrative messag of first terminal broadcasting, to the response message of first terminal transmission for administrative messag.

The hypothesis first terminal takes the lead in opening in the embodiment of the invention, and become the office terminal, the second terminal starts after first terminal is opened as being managed terminal again, and the third terminal conduct is managed terminal and restarts after the first terminal bandwidth that has been the second terminal distribution.And the second terminal and third terminal are not assigned with any bandwidth when starting, carry out allocated bandwidth but by the office terminal unification each is managed terminal.

The address and the bandwidth demand amount that comprise the second terminal in the described response message for administrative messag, so that first terminal is judged when remaining bandwidth is not less than the bandwidth demand amount of the second terminal, distribute bandwidth also will be assigned with the address adding address list of the second terminal of bandwidth by the bandwidth demand amount; At this moment the first address list records the address of the second terminal.

405, after first terminal receives the response message for administrative messag of the second terminal transmission, judge whether remaining bandwidth is not less than the bandwidth demand amount.

First terminal judges according to the bandwidth demand amount in the response message whether remaining bandwidth that the user accesses total bandwidth is not less than the bandwidth demand amount of the second terminal, and wherein, the user accesses the access bandwidth that total bandwidth is the IPTV business that all have been opened in the home network.

406, when remaining bandwidth is not less than the bandwidth demand amount, presses the bandwidth demand amount and distribute bandwidth.

In the embodiment of the invention two, for convenience of description, third terminal starts after first terminal is the second terminal distribution bandwidth, namely in the rear startup of step 406.

407, first terminal will be assigned with the address adding address list of the second terminal of bandwidth.

408, first terminal is broadcasted the administrative messag that comprises address list by the default management cycle in home network.

The administrative messag that first terminal will comprise address list broadcast away by the default management cycle, so that when being assigned with the second terminal of bandwidth and in address list, finding the address of self, and startup IPTV business.

Because third terminal starts after step 306, therefore the second terminal and third terminal all can receive the administrative messag of first terminal broadcasting in the step 408.

409, when finding the address of self in the address list of the second terminal in administrative messag, it is professional that the second terminal is opened IPTV.

In the actual scene, when the office terminal is gone on the air administrative messag for the first time, may there be a plurality of terminals as the non-management person (here take terminal A and terminal B as example) to start, then terminal A and terminal B can receive administrative messag, and feedback response message, so that being terminal A and terminal B, the office terminal distributes bandwidth.

410, after third terminal receives the administrative messag of first terminal broadcasting, send response message to first terminal.

Third terminal starts after the second starting terminal, concrete, be after the first terminal bandwidth that has been the second terminal distribution, to start, so third terminal do not receive the administrative messag before the step 406, but third terminal has received the administrative messag that first terminal sends in step 408.Afterwards, third terminal sends response message to first terminal, comprises address and the bandwidth demand amount of third terminal in this response message.

411, after first terminal receives the response message of third terminal transmission, judge whether remaining bandwidth is not less than the bandwidth demand amount of third terminal.

412, when remaining bandwidth is not less than the bandwidth demand amount, be that third terminal distributes bandwidth by the bandwidth demand amount.

413, first terminal will be assigned with the address adding address list of the third terminal of bandwidth.

414, first terminal is broadcasted the administrative messag that comprises address list by the default management cycle in home network.

415, when finding the address of self in the address list in administrative messag, it is professional that third terminal starts IPTV.

Further, in embodiments of the present invention,, after being assigned with bandwidth and starting separately IPTV business, also need to keep heartbeat with first terminal and be connected as the second terminal that is managed terminal and third terminal.Concrete, first terminal sends administrative messag according to the management cycle, and the second terminal and third terminal feed back the administrative messag that receives, and are in opening so that first terminal is confirmed the second terminal and third terminal.

On the other hand, when remaining bandwidth during less than the bandwidth demand amount, can not carry out allocated bandwidth as the first terminal of office terminal.For instance, if the bandwidth that third terminal requires exceeds the scope that first terminal can distribute, then first terminal can not distribute bandwidth to third terminal, and the address of third terminal can not added address list yet.Can not find the address of self in the address list of third terminal in administrative messag, this moment, third terminal can continue to send the address that comprises third terminal and the response message of bandwidth demand amount, in order to require bandwidth to first terminal.

Need to prove that the value of the management cycle described in the embodiment of the invention and stand-by period can pre-set according to actual use scenes.

The embodiment of the invention provides a kind of method that realizes bandwidth control, behind certain starting up of terminal in family's network, at first login in the IPTV operation system, after logining successfully, obtain the user from the IPTV operation system and access total bandwidth, be kept in the terminal, and judge whether within the default management cycle, to receive administrative messag, when not receiving administrative messag, current terminal is broadcasting election message in network then, the election office terminal; When receiving administrative messag, current terminal sends response message to the office terminal, the address and the bandwidth demand amount that comprise current terminal in this response message, after the office terminal receives this response message, judge when remaining bandwidth is not less than the bandwidth demand amount that is managed terminal, the address that is managed terminal of distributing bandwidth also will be assigned with bandwidth by the bandwidth demand amount adds address list, the office terminal continuation will comprise the administrative messag of address list and broadcast in home network, when being managed terminal and in address list, finding self address, start IPTV professional, thereby avoided when the remaining bandwidth deficiency, and when the same IPTV of a plurality of terminal accesses is professional, can guarantee that at least one terminal carries out Operational Visit glibly.

Embodiment 3:

When having an office terminal and at least two to be managed terminal to be present in the home network, the office terminal is managed terminal to each and manages, if office terminal shutdown this moment or disengaging home network, then need to select a new office terminal in the terminal in all being managed, for realizing this purpose, the embodiment of the invention provides a kind of method of bandwidth control, as shown in Figure 5, comprising:

501, the office terminal is by default management cycle broadcast management messages in home network.

Comprise address list in the administrative messag, record the address that is managed terminal that is assigned with bandwidth in the middle of the address list.

The above-mentioned default management cycle of mentioning specifically can be 1 second cycle.

After the office terminal shutdown or breaking away from home network, continue to carry out subsequent step 502 to 504.

502, when being managed terminal and within the default management cycle, not receiving described administrative messag, broadcasting election message in home network.
